feat(geometry/manifold/bump_function): define smooth bump functions, baby version of the Whitney embedding thm (#6839)

  • refactor some functions in analysis/calculus/specific_functions to use bundled structures;
  • define to_euclidean, euclidean.dist, euclidean.ball, and euclidean.closed_ball;
  • define smooth bump functions on manifolds;
  • prove a baby version of the Whitney embedding theorem.
